Adds method to calculate 1D median and quantiles and customise corner titles
- The method to calculate median and 1-sigma quantiles draws heavily on corner.py and is credited. In future, we may want to generate tables for which this may be useful.
- The titles in corner.py have changed from "label=median+/-1-sigma" to just "median+/-1-sigma".
- The previous behaviour can be recovered by giving
plot_corner
the commandshow_titles
.
